After I Transmigrated into a Book, I Got a Happy Ending with the Villainous Prince

A sharp-tongued but soft-hearted heroine, brave and resourceful, paired with a seemingly aloof villain with a rich inner world

The heroine transmigrates into a historical romance novel, becoming the doomed, beloved woman who dies taking a sword meant for the male lead. Her death is horrific.

But to complete the System's mission and follow the entire plot, she goes to take a sword for the male lead. Unexpectedly, she takes the blow for the villain instead, and the storyline begins to collapse. She was supposed to be able to return home, but now she's trapped in the book.

The villain's storyline has been thrown into disarray too. The heroine wants to flee with him to Jinzhou, but the male lead's people are stationed there, so he begins to suspect her. After she explains herself, he remains somewhat doubtful but still believes her. And because she took a sword for him, he even convinces himself that she likes him, so he escapes the pursuit with her.
